Blaise de Wolfe risks losing De Wolfe Hall unless he can prove his pure Norman ancestry and be eligible for a substantial renovation grant from the "Sons of the Conquest", an exclusive club. He turns to family tree researcher Anne Smith, unaware of her Norman roots and consequent disdain for the male-only policies of the club. Sparks fly between them when she digs up some unexpected information about Blaise's medieval ancestor, Gaetan de Wolfe.
Anne harbors other resentments. Widowed when her husband volunteers for a second tour with the British Army in Iraq, she is reluctant to embark on another relationship, though she is drawn to Blaise. He too is afraid to risk his heart after his fiancee dumps him upon learning his ancestral home is draining his bank account.
